Hearst’s[] works was based on classification of documents using sentiments. A text based systems should provide more information about the content apart from what the standard information retrieval system provides. This is should be done in a manner by avoiding complex and resource consuming behaviour of understanding the contextual meaning. His idea is to approach document discovered based on directionality of the sentence. This is carried out by coercing the sentences into smaller metamorphic models for better semantic understanding and interpretation. In this manner, the directionality of the sentence can be easily obtained. Similarly, Sack’s[] research based on the context of information retrieval is to build a system that could recognise
